Jeff,
My guess is that it could be:
1) Bad wireless card/maybe old driver version in the laptop. I had the
same problem at another location. Signal would drop on large transfers
and any old time it felt like it. Sometimes you would swear that there
was a real pattern to it. Once I replaced the laptop wireless card it
worked fine. I also had an issue with driver version when testing. The
newer version had better performance. It was a Broadcom B/G card if that
helps.
2) Bad Router, or like you mentioned, possibly some neighbor with a
powerful 2.4GHZ phone or microwave (but probably not as likely).
To start with, try another wireless device and see if you have issues.
If you are around Park Slope, I can give you hand and you can test with
my gear.
